A student newspaper reports that most students go to sleep at 1:30 am. Even if that’s an overstatement (夸张), it’s close to the truth. Scientists say teens should sleep nine hours each night. But that’s hard. Some are even “pulling all-nighters” (开夜车). These students must hand in their homework the next day but they haven’t done it. In the morning they don’t look healthy and you can tell who’s been doing it. One of my classmates did a survey on the topic. She found that most kids pull all-nighters to finish homework, but some do it for other reasons, such as playing computer games!
Maybe our lack(缺乏) of sleep is because of laziness — I think I’m a rather lazy student — or maybe it’s because we have too much to do in American high schools. I usually go to bed around midnight. If I stayed up past 1:30 am, I wouldn’t get any work done. I’d be falling asleep at my computer. My classes begin at 7:30 am. I’m partly awake in my first class. By the second, I’m a little sleepy. By my third class, I’m sleepy. By midday I’m finally fully awake. But by 3:00 pm, I’m slowing down again. Yet I get more sleep than usual students.
Most American high schools seem to have a similar(相似的) problem with sleepy students. High school classes start at 7:30 am, so students have to get up one and a half hours before that to get ready and catch the bus. It’s believed that lack of sleep can be bad for both grades and health. Some schools are paying attention. Classes in those schools start at 8:30 am.
【小题1】What does the underlined sentence “it’s close to the truth” mean?

Every day when Cora Castle, 14, from Indiana, US goes back home, she opens her computer and logs into a website（登录网站）called Fuel Up to Play 60.

    She puts on what she has eaten and what kind of activities she has played that day. Then the site decides whether Castle has eaten healthily and done enough exercise.

    All the seventh graders in Castle's school have done the same thing since the year started. It's part of their health class.

    If the site finds her habits are unhealthy, it will give her advice. If she does something good, the website will give her a star.

    Her health teacher set up a competition to see which student could get the most stars from the website. Castle has got 30 stars so far.

    Cameron Bartlett said she liked tracking（跟踪）the food and activities. "This is the first year we've done it," she said. "It's really interesting to see all of the different choices that we have."

The seventh grade health class is coming to an end. They won't be in health class, but the students all said that they would go on to take part in the Fuel Up to Play 60.

    "There's lots of bad food out there that we've all been eating," Bartlett said "This really helps all of us eat healthier food."
